Key not working in car door lock.

rosie383

The driver's side lock on our 2006 Honda Jazz is not working. The key won't go all the way in and definitely won't turn.
It works easily in all the other locks and the central locking mechanism is fine, even for the driver's door.
This happened a few weeks ago and a squirt of WD40 did the trick. This time I have sprayed it again, but no joy.
What else can we do? Would squirting some hot water in help?

Can anyone help please? Just hoping someone may see this now and can give us an idea what to do please.

Try repeatedly "loading" the key blade with WD40 and inserting and removing it.

Obviously don't force it! But try slight pressure from side to side as you insert the lube coated key and see if you can get it to work.

Do you think some nut job may have squirted glue in it?

While WD40 is a handy, multi-use spray, it does locks no good at all. Try to get some powdered graphite, or rub the key with a pencil to lubricate the lock. Anything else will work temporarily and then gum up the lock again with the dirt and gunge it attracts.

Agreed, WD will make matters worse in the long term.

Graphite is the best option, tho' I'm not sure it will help in this case, it sounds like someone has stuffed something in to it.

Colino and Inactive beat me to it- was just about to suggest blowing in graphite from a pencil....

Thanks for all the suggestions. Maybe the problem is because we used wd40 the first time it seized up. Will try the pencil trick and hope it works. I suppose it works on zips, so why not locks? Only question is, if it has already got 'gunk' in it, surely, if I introduce graphite too, will that not just compound the problem? My dh friend who is 'handy' with cars, suggested syringing in some hot, soapy water to try to clean the mechanism a bit. Anyone tried that?
